WAB query widget can't format date for non-UTC data?

I have data in SDE in Pacific time (-8 UTC). In my map service (not feature service), I've time-enabled all my layers and set the timezone, so the timestamps show up correctly in my web map (as a user who is also in Pacific time).

However, I have a web app query widget where I want to look for Calibrations that were done today. No matter what option I try, it always shifts the time by 8 hours to "accommodate" my local time.
